Terpenes represent the largest and structurally most diverse group of natural products. Since ancient times, humans have used terpenes contained in essential oils as medicinal agents, preservatives, and fragrances in their ...

An improved synthetic method affording 4-chlorocoumarin-3-sulfonyl chloride (4) in very good yield (ca. 85 %) is reported. This compound was reacted with various bidentate nucleophiles such as 2-aminopyridines and ...

Calcium orthophosphates (CaPs) are important in geology, biomineralization, animal metabolism and biomedicine, and constitute a structurally and chemically diverse class of minerals. In the case of dicalcium phosphates, ...

A hierarchical system of highly porous nanofibers has been prepared by electrospinning MOF (metal-organic framework) nanoparticles with suitable carrier polymers. Nitrogen adsorption proved the MOF nanoparticles to be fully ...

Die Untersuchung von schwer zu erreichenden Hohlräumen durch schmale Zugänge wird im technischen Umfeld als Boroskopie und in der Medizin als Endoskopie bezeichnet. Wenn neben der reinen Inspektion auch eine Manipulation ...

Two-photon polymerization (2PP) is applied for the fabrication of 3-D Zr-Si scaffolds for bone tissue engineering. Zr-Si scaffolds with 150, 200, and 250 μm pore sizes are seeded with human bone marrow stem cells (hBMSCs) ...

Buried explosive material, e.g., landmines, represent a severe issue for human safety all over the world. Most explosives consist of environmentally hazardous chemicals like 2,4,6-trinitrotoluene (TNT), carcinogenic ...

Sandwich-structured composite zeolite membranes with enhanced hydrogen selectivity were prepared on porous α-Al 2O 3 supports by using 3-aminopropyltriethoxysilane as an interlayer. © 2012 The Royal Society of Chemistry.

Covering: 2005 to 2013 In this review recent progress in the development of heat shock proteins (Hsp90) in oncogenesis is illuminated. Particular emphasis is put on inhibitors such as geldanamycin and analogues that serve ...
